The present invention provides an LCD capable of being driven with various frequencies without deterioration of image quality. According to the present invention, a method of driving an LCD in two-dot inversion for a low vertical frequency and in one-dot inversion for a high vertical frequency is provided. The method determines whether the vertical frequency of the LCD changes, changes the inversion type into one-dot inversion if the vertical frequency is changed from a low frequency to a high frequency, and changes the inversion type into two-dot inversion if the vertical frequency is changed from a high frequency to a low frequency. Moreover, if a flicker is generated when driving in one-dot inversion, the inversion type is changed into two-dot inversion. To avoid the unequal charging generated in the LCD driven in two-dot inversion, the pulse width of the gate signals are adjusted after measuring the load of the data line.
